Hiya, My hilix occasionally when driving will go into what i will call limp mode. Its like the turbo dies and i cant do over maybe 10kms. Switch the car off for 5-10mins and its good to go again. I took it to toyota today and they said it could be the accelerator and for $1000 + labour. They will replace it. And it may fix the problem. Any ideas???.
